Tierra Alta were the first kennel to introduce the Mastin del Pirineo to the U.S.A. Our kennels have produced excellent show potential pups bred from the finest imported and now domestic stock available - Tajadera del Tio Roy, Castillo de Ali, Do Limoeiro, De Domus, El Bellotero, Rocaforte, Larresalkoak, Del Paso del Oso, Moralet, Wela Brillante, Springstrand, Iirismaan, Bondadoso and Farma Stekot, Murtoi's, Del Mostin and Can Cabot. Our foundation mostines are imports directly from Spain, Italy, Finland and the Czech Republic. Our kennels have also exported to Canada, Europe and Mexico. Our kennel has the broadest bloodlines for the PM in the U.S.A. and the largest number of Pyrenean Mastiffs in the country.

You will find our mostines enjoying life with their families - many as wonderful family companions, many in the show ring, others still doing the job of their ancestors and protecting the flocks, there are those that are involved with their owners in therapy programs and bringing happiness to the elderly and young children and some may be seen from time to time in movies and TV. Whatever their activities may be most who encounter the mastin for the first time fall in love with our breed as we did years ago.

A Moment In History!

Breeder of Pyrenean Mastiffs since 1996: Tierra Alta kennels were proud to announce the arrival of the first Pyrenean Mastiff litter born in the U.S.A. October 1st, 1997

A documentary and history of the Pyrenean Mastiff (Mastin Del Pirineo) filmed twenty years ago in the Spanish Pyrenees mountains. In 1998, our travels took us to Spain to meet with the Spanish breeders and learn more about this wonderful breed.
